This works on the invariant that all jumps in the given blocks are required. Starting from there we try to make a few more jumps redundant by reordering them.
type InstrBlock = OrdList Instr Source #
InstrBlocks are the insn sequences generated by the insn selectors.
They are really trees of insns to facilitate fast appending, where a
left-to-right traversal yields the insns in the correct order.
